The ASL Crypto Manager program is intended for fast encrypting of any users files. For this purpose, RC4, a high-speed on-the-fly algorithm of encrypting, is used in the program. The program allows to encrypt any taken file and to pass it safely to the other person, using the common ways (portable data medium, e-mail message, local area network, etc.). Prior to the encrypting of any file, a key word is being set up; without knowing the password, it's impossible to decrypt the file by means of any program or any other way. The program also allows to carry out encrypting of multiple files (encrypting of several files at one pass) with identical or different passwords. After encrypting, the program creates a file with *.cmf (Crypto Manager File) extension in the folder of the source file or at the place specified by the user. The options allow for saving or deleting of the source file after encrypting. Any attempt for opening the encrypted file leads to its opening in the ASL Crypto Manager program (if the program is installed on the computer). The distinguishing feature of the program is that the program offers two options of password input: the standard and the safe ones. The standard input is using the keyboard. The safe input is performed by means of the mouse and the on-screen keyboard. The second option of input excludes the possibility of intercepting the password by the keyboard spy (key logger), as the keys on the keyboard are not pressed. The safe mode of input is accessible only for the registered version of the program.
